SPECIFICATION forming part of Letters Patent No. 252,942, dated January 31, 1882 Application filed December 9, 1881. (No model.)

To all whom it may concern Be it known that we, FREDERICK E. I-InINiG, of Louisville, in the county of Jefferson and State of Kentucky, and MAX LINDENTHAL, of

the city, county, and State of New York, have invented certain new and useful Improvements in Stair-Rods,of which thet'ollowing isasprcification.

This invention relates to an improved stair 1o rod, which is attached to the step in such a manner that it resists the strain exerted thereon by the stair-carpet while in use, but which admits the ready removal of the rod when taking up the carpet and lifting it away from the step.

The invention consists of a pair of clamping or retaining plates, made of any material desired, one of which is to be attached to the step, and one or both of which are provided with teeth to engage the carpet caught between them, said plates being secured by springclasps and fasteners at the ends thereof.

In the accompanyingdrawings, Figure 1 rep- .resents a perspective view of our improved stair-rod,shown as applied for use. Figs? and 3 are detail views of the base and top plate of the stair-rod as detached from each other. Fig. 4 is a vertical transverse section of the rod through the fastening end-clasp. Fig. 5 0 is a perspective view of a modified construction of the same.

Similar letters of reference indie-ate corresponding parts.

A in the drawings represents the base-plate 5 of our improved stair-rod, which plate is permanently attached to the step of the stairs, close to the riser thereof, and is provided along one edge with upwardly-bent teeth a, which take hold of the carpet, and at each end with bent-up flanges l), as shown clearly in Fig. 2.

B is the upper retaining plate, adapted to fit over the base-plate, and to be secured thereto by means of spring clasps or catches O O, which engage the flanges b I) of the baseplate 5 A, as shown in Fi 4. This upper retainingplate, B, is also provided along one'edgc with projecting teeth d d, either continuously along the entire length thereof or at intervals thereon, and is formed with an inwardly-bent front edge, e, as shown in Fig. 3. \Vhen the top plate, B, is placed in position upon the baseplate A, with the stnir carpet placed betweein them, the teeth of the base and top plates bite into the carpet and secure it firmly, so

as to resist any vertical or horizontal strain exerted thereon.

When it is desired to take up the carpet the top plate, B, of the lowermost stair-rod is removed, and then the carpet is taken ofi and lil'ted away from the steps, by which operation the top plates of each step are successively lifted out of their base-plates, and thus the carpet may be quickly removed.

Instead of forming both plates with serrated edges, as described, one plate alone may be provided with bent-up teeth aong both edges, the teetlrextending along a part of or along the whole length of the plate, as desired.

A modification from our invention is shown in Fig. 5, in which the base-plate A is dis- 7o pensed with and a single stair-rod plate, 13, used, which is provided with bent-up teeth along both edges. This single plate B is provided with spring-clasps U at the ends, which are secured to fasteners attached to the steps of the -stairs,'they corresponding substantially with the ends b b of the plate A, the spring-clasps engaging the fasteners in the same manner as is shown in Fig. 4.

Our improved stairrod may also be applied to the riser below the step, as shown in Fig. 1, in connection with small pieces of carpet coveringeach step separately, such an arrangement having many advantages-as, for instance, the cleaning of each step separately with great ease and quickness, economyof carpet material, and facility for removal. In case of wear, one or more steps can be taken up and replaced by new ones,saving the expenses of a whole carpet, and in case of removal it permits the use of the same piece 'of carpet upon other stairs independent of adifference in the height of the riser.

Having thus described our invention, we claim as new and desire to secure by Letters 5 Patent 1.
